WALL-Lime.

in the county of Douglas and State of New braska, haveinvented'certain new and useful Improvements in lVall-Linings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

' The present invention relates to linings for the walls of refrigerators, cooling rooms, houses, and the like where heat insulation is desired. i

The object is to provide an insulating lining of thischaracter which is made up of blocks adapted to be assembled in interfit ting relation for adapting the lining to angles, corners, andvarious configurations of a wall for effectually insulating the wall provide a linlng which is composed of'a' multiplicity of cellular blocks, the spaces of which are adapted to be closed and sealedby' the interfitting and securing of the blocks together; and to provide a wall lining block constructed of fibrous cellular material so arranged as to produce a relatively strong and durable'block capable of withstanding considerable pressure.

A further object is to peculiarly form the fibrous cellular block so that when a pair of blocks is arranged in end abutting relation a plastic adhesive may be applied to the abutting ends of the blocks with the. adhesive closing the pores of the block and insuring a firm purchase of one block upon the other when the adhesive is set. I

With these and further objects'in view as will hereinafter in part become apparent and in part be stated, the invention com- -prises certain novel constructions, com-binaparts assubse Fig. 2 is a perspective View of a numberof the wall lining blocks of \this invention separated and'shown in their relative posiedges, and-as the flanges 11 and 12 are Specification of Letters Patent.

tions for-assemblage to form a'corner of a wall lining or the like.

Fig. 3 'is an enlarged side elevation, partly in section, of one ofthe blocks, showing the crossed arrangement ofthe corrugated sheets and the interposed plain sheets which form one of the sections of the block.

Fig. 4 is a fragmentary, enlarged section through the meeting ends of a pair of the blocks, showing the application of the plastic adhesive to the abutting ends.

Fi 5 is. a'fragment-ary section taken substantlally on the plane indicated by the line it m of Fig. 4, showing a longitudinal section through the joint between apair of abutting block's. p

Referring to the drawings by numerals, the wall lining is composed of a plurality of blocks or sections 10 adapted to be assembled as shown in Fig. 1 to provide a wall lining of the desired extent. The-blocks '10, as shown ,to advantage in Figs. 2 and 3, each comprise a pair of sections which are ofiset diagonally relatively to each other and secured in face engagement to form a block having outstanding flanges 11 and 12 at ad- 8 jacent sides and of a thickness 'equal to substantially that \of one-half the thickness of the block.- A pair of blocks may thus be interfitted or overlapped at their flanged formed on adjacent edges or sides, it is apparent that one block is capable of interfitting in either straight or rectangular relation with two other blocks, as indicated in Fi 2, for forming a corner of the wall or linmg. The said other two blocks 10 each have one of their flanges interfitting with the respective flanges 11 and 12 of the first block, and when the two blocks are arranged in right-angular relation to the first block the free flanged edges of the two blocks may be int/erfitted to complete the corner structure. l

The two sections of each block are formed with corrugated faces 13, and the faces 13 are adapted to be brought together in assembling the sections of the blocks and interfitted, as shown in Fig. 4, to maintain the sections from relative dis lact and to form relatively large surface areas for the adhering faces of-the sections. The rojecting edge of one section which forms the flange 11 expose the corrugations beyond the marginal edge of the other section and the corrugations may extend, as shown in the present disclosure, substantially in parallelism with the marginal edge of the other section. The adjacent-flange 12 exposes the corrugations as extending outwardly from the adjacent edge of the other section, and the corrugated faces of the flanges provide relatively large surface areas for not only firmly interlocking with adjacent blocks but also to receive a relatively large quantity of adhesive for insuring a tight sealed joint between adjacent blocks. It is obvious that the other section of the block provides similarly arranged and formed flanges Hand 12, the other flanges, however, facing toward the opposite side of the block.

As shown in Fig. 3, each section 0f\the block is formed of a plurality of corrugated fibrous layers 14 arranged with their corrugations extending in directions at right angles to each other to form a crossed and inter braced structure. The corrugated sheets 14: have interposed therebetween plain, flat sheets 15 of any desired thickness for maintaining the corrugated sheets in proper form, and for forming in the block section an extremely large number of independent air cells. The corrugated and flat sheets 11 and 15 are thus alternately superposed one upon the other to form a section of the desired thickness, the laminations preferably terminating in a flat smooth sheet at the outer face of the block. f

The air cells formed in the block sections are closed when the blocks are assembled, and a plastic adhesive 16 is laced between the meeting ends of the bloc s in sufficient quantity to be forced into the cells or pores of the sections and provide, when the adhesive sets, a relatively strong, substantially integral joint for the blocks. The adhesive also insures the sealing of the cells or spaces and thus entraps air therein so that an eifective insulation is formed. The blocks may be made of any desired size and shape, and any desired number of the same may be employed for building up a wall or lining of the required dimensions. The sections of each block may also be of the desired thickness by superpo'sing the desired number of layers 14 and 15 so that the completed wall or lining may be given the desired thickness.

What I claim is i Q 1. As an article of manufacture, a fibrous wall lining unit comprising a pair of super posed offset sections secured to ether in face engagement and having inter tting corrugations at their meeting faces for interlockisaaoea posed diagonally 0 set sections secured together in face engagement and with corrugated abutting faces adapted to interfit and form outstanding flanges at adjacent edges of the unit with. corrugations extending in directions at right angles to each other. 3. In a wall structure, the combination of a pair of units having marginal flanges adapted to overlap-and provided with air cells in the units opening at the marginal edges thereof, and a plastic adhesive embedded in the meeting edges of the units and adapted to close the air cells and secure the units together.

4. In a wall structure,the combination of a pair of fibrous units having air cells there- .in opening through the marginal edges of the units, the units provided with flangesat their marginal edges adapted to overlap, and a viscous adhesive packed between the meeting edges of the units and into the ends of the air cells for uniting the units and closing the air cells to form dead air spaces in the wall structure.

5. Asan article of manufacture, a fibrous wall unit comprising a pair of sections and each section composed of superposed alter-- nate flat and corrugated fibrous sheets se curedtogether to form cells in the sections, the sections terminating at one face in a corrugated sheet and at its other face in a flat 'sheet, and the sections secured in face engagement with their interfitted. l

6. As an article of manufacture, a fibrous wall unit comprising a pair of superposed sections ofi'set relatively to each other for exposed corrugations.

forming a marginal flange on the unit, each a section composed of a plurality of layers of cellular fibrous material with the corruga: tions of the alternate layers extending at.

the other section and to provide a corrugated exposed surface to the marginal flange.

In testimony whereof I a'flix my signature in presence of two witnesses.
